PANews reported on January 15 that in response to a tweet from Brett Harrison, former president of FTX US, SBF said that Brett is a great developer with a deep understanding of FTX's products. Although I strongly disagree with most of what he said, I don't want to argue with him publicly, and I don't think I am qualified to publicly accuse him of his work performance unless he authorizes me to do so. I am saddened by what happened to all FTX employees and wish him all the best. Previously, Brett Harrison, former president of FTX US, tweeted a review of his work experience at FTX, saying that SBF was "emotionally unstable" and strong during his tenure at FTX US, and that the relationship with SBF and his deputies had completely deteriorated, and the two sides had been arguing over FTX's management style for months.
